+.PP
 A few platforms such as FreeBSD and NetBSD recognize termcap names rather
 than terminfo capability names in their respective \fB@TPUT@\fP commands.
+.PP
+Most implementations which provide support for \fIcapname\fR operands
+use the \fItparm\fP function to expand parameters in it.
+That function expects a mixture of numeric and string parameters,
+requiring \fB@TPUT@\fP to know which type to use.
+This implementation uses a table to determine that for
+the standard \fIcapname\fR operands, and an internal library
+function to analyze nonstandard \fIcapname\fR operands.
+Other implementations may simply guess that an operand containing only digits
+is intended to be a number.
